SYNOPSIS
pacman -S [OPTIONS] [PACKAGE...]
DESCRIPTION
pacman -S (sync) synchronizes packages from remote repositories. It downloads and installs packages, updates the system, and manages the local package cache on Arch Linux systems.
PARAMETERS
-S, --sync
Synchronize packages from remote repositories-y, --refresh
Download fresh package databases from the server-u, --sysupgrade
Upgrade all out-of-date packages-s, --search regex
Search package names and descriptions-i, --info
Display detailed package information-c, --clean
Remove old packages from the cache--noconfirm
Skip confirmation prompts--overwrite glob
Overwrite conflicting files--downloadonly

CAVEATS
Always run -Syu together to ensure database and packages are in sync. Running -Sy alone can cause partial upgrade issues. Use -Syyu to force refresh even if databases appear up to date.
HISTORY
pacman is the package manager for Arch Linux and its derivatives, designed with simplicity and speed as primary goals.
